Contrast-induced ischemic colitis following coronary angiography: A case report

Figure 1 Coronary angiography. A: Localized stenosis of 50%-70% at the middle segment of the right coronary artery; B: Diffuse stenosis of 50%-70% from the proximal to middle segment of the left anterior descending artery.

Figure 2 Abdominal computed tomography scan (axial plane). A: At 9 h post- coronary angiography (CAG), computed tomography revealed thickened right colonic wall accompanied by multiple exudative changes indicating inflammatory lesions; B: On the 3^rd day after CAG, edema and inflammatory exudate became more serious.

Figure 3 Contrast-enhanced abdominal computed tomography scan on the 3^rd day after coronary angiography. A: Coronal plane; B: Sagittal plane showed thickened colonic wall corresponding to the ascending and right transverse colon segments and multiple exudative changes.

Figure 4  Contrast-enhanced abdominal computed tomography scan demonstrated no thrombus in the superior and inferior mesenteric arteries and veins.
